To all whom it may concern:

Beit known that I, HUGH A. KINGsLAND, a citizen of the United States,residing at Newark, in the county of Essex and State of New Jersey, haveinvented new and useful Improvements in Machines for Inserting LaeingvStuds, of which the following is a specification.

-My invention relates to improvements in machines 'ff-'or inserting.lacing studs of the ,serew type7 into shoes, my objectbeingtoprovide'forthe rapid and accurate insertionv novel andpeeuliareonstruction of the operating parts, and by makingthe feeding ofthev of such studs,'whicl 1 object I accomplish by a studs to themachine and their insertion bythe same entirely automatic. j l myinventionconsisty The lnovelfeatures of in the combination of a chuck, amechanism 'for imparting a rising and falling -motiou and for rotatingthe same, a lfeeder automatically delivering the-lacing-studs, one at atime, Va conveyer for receiving the same from the feeder und insertingthem into` the chuck, and a punch which fixes the studs in the shoe, allof which" is more fully pointed out inthe following specification andclaims, and illustrated in the accompanying drawings, in Whiching theparts in the position they occ'upy after the chuck has been rotatedto'insert thelacingstud into the material. Fig.l 6 is a sectional plan'or top view showing the mechanism of the conveyer inthe operation ofinserting a stud into the chuck. Fig. 7 is a similar view showing theconveyer in its normal position.

Similar letters indicate corresponding parts. In the drawings, theletter A, Fig. 1, designates the feeder-containing mechanism for feeding'the lacingstuds B, one ata time, to the inserting mechanism.

Gis an oscillating conveyer which receives the lacing-studs, one at atime, from the feeder A and lconveys the same to and inserts them in achuck, D. The lacing stud shownin this example in Figs. 10 and 11, andfor the reception of which this chuck is especially constructed,consists of an open or soeketed head having an eccentric shank, b,and aconcentric shank having at its head aspiral or screw, b', which isintended to be screwed into the material, the latter-being previouslyperforated, as at biin Fig. 14., to allow the spiral or screw Afterinsertion of the stud its spiral or screw is ,flattened out, as in Figs.12'and 13, whereby it is firmly secured' in place.

The chuck D, Figs. 1, 6, 7, and 9, is constructed in cap form, and hasin its upper end a socket or jaw, d, which receives the lacingstud fromthe conveyer. This socket opens laterally, and is so 4constructed thatthe stud can slide therein, provided-its eccentric shank b is at therear; andthe chuck contains a nose, d,'whichl enters the head of thestud, so that said stud isheld firmly and cannot rotate or yield as thechuck rotates. The chuck D fits over theV end of a vertical spindle, E,to which IOO lit is connected by a. pin, e, which extends through aslot, e', in the latter. On the upper v its vertical motion is limitedbya sleeve, d3,

with which a shoulder on the former comes into contact. This sleeve iscut away or provided with a way or channel for the passage of thelacing-stud to the chuck.

The conveyer C, Figs. 1, 6,7, and 8, is situated on the upper portion ofthe casing F, and oscillates in a horizontal plane. It receives Athelacing-studs from a tube, A',-Fig. 1, in which latter they descend fromthe feeder A, always in the position shown in Fig. 10-that is, headdownward. The conveyer consists of a body, G, circular inform, which isrigidly attached to the casing F, and a cover or disk, G', which isattached to a spindle, g, extending downwardlyand having bearings in thebody G and the casing. A space is formed between the body and cover by ahuband a circular ledge or wall, g2, on the body, and between the bodyand cover are the operating parts of said conveyer. v

In the periphery of the cover'G, Fig. 8, is formed a recess, r/,whieh isdirectly under and inline with the feed-tube A' when the conveyer is inposition to receive alacing-stud. Aguidelever, H, provided with asocket, is hinged at h to the body G, Figs. 6 and 7, and is pressedoutward by aspring, h', as inFig. 7; but when the conveyer is inposition to receive thelacingstud, Fig. 6, it is pressed inward an'daids in forming a socket for the reception of the latter. 'lvhisthrowing inward of the lever H is accomplished, by a pin, h2, on thelcover G', which engages a tail, It, on the said lever as the covermovesv toward the feed-tube A', Fig. 6.

To hold the lacing-stud against the circular ledge or Wall g2 on thebody G as the cover G rotates in the direction of arrow 1, Fig. '-7, to-

ward the chuck D, I provide a lever, I,which is pi'voted at t', Figs. 6and 7, to the cover. .One arm of this lever is acted on by a spring,y

t', which presses the other arm inward, and

this latter arm has a portion cut away to form a-jaw, 2, Fig. 7,'Whiehjaw enters' the socket in the head of the lacing-stud and comes almostbut not into actual contact with the eccentric shank b, and thus holdsthe lacing-stud. The lacing-stud, as before stated, can onl'yeuter thechuck D when in one position-wiz., with the eccentric shank bin therear', and it will be observed that this lever I, owing to the formationot its jaw twill always turn the stud, no matter how it may enter theconveycr, intov the proper position. The lever` I is actuated to openwhen the conveyer is in its receiving position by a pin, t,.on lthe bodyG, which engages an inclined cam-surface on one arm of said lever. Thecover G', Fig. 9, in rotating, conveys the lacing-stud into a -line withthe socket d in the chuck D, whereit is deposited on the reversal of themotion of said co er. The stud is inserted into the chuck by aspringpressed bolt, J, which is guided i'n suitable Ways, j,.in the bodyG, and is actuated, as the cover G', Fig. 7, reverses, by a lever, J'1one arm of which engages .the rear of the bolt. The other arm of saidlever is provided with a tooth whiehis engaged by a spring-pressedtoothed catch, J2, carried by and pivoted to the cover. rIhe spring j',engaging the bolt, returns the latter to the position shown in Fig.

`(i. The catch J 2 is caused to release the lever J' by a cam-surface,j?, on the body G, which engages said latch.V ,T he means for actuatingthe cover G' in its oscillatory motion will be presently explained.

On inspecting Figs. 1, 6, 7, and'9 it will be observed that the chuck D,before receiving the stud', is depressed, Fig. 9, so as to bring thesocket d thercin'on a level with lthe conveycr, and when it is ready tobe rotated for the insertion of the lacing-stud it is elevated, as inFig. 1, this elevation being .necessary in order to place the work outhe chuck, The motions necessary to be imparted to the chuck aretherefore, first, an upward motion, after the reception of the stud,then a rotary motion for its insertion, and, finally, a downward'motionto thelevel of the conveycr, for thereception of the next lacing-stud.Thesemotious I obtain as follows: The lower` end of the chuck-bearingspindle E is socketed, so as to allow lthe rotation of the spindleaboutits vertical axis, in a wedged-shaped carrier, K, Figs. l and 9,which latter can move vertically in ways in the easing F. This carrier Kis connected by a dovetail joint with a reciprocat- IOO ing slide, K',having an inclined working-face,

k,- so that when the said slide is in the position shown in Fig, 9 thechuck is drawnt'o its lowest or'receivingposition, -and when 'in theposition shown in Fig; ylis moved to its highest or inserting position.The slide K' is guided by a block, lc, Figs. 1,-2, and 4, which extendsfrom a post, k", on the frame, and enters a longitudinal slot, 7c, in-said slide. A flat spring-k3, bearing on the slide, retains it in anyposit-ion it may be placed.

To the main shaft L of the machine is loosely secured, so as to turnabout the same as an axis, a crank-lever, ZL', one arm of which isconnectedwith a treadle (not shown. in the drawings) by a rod, Z', Fig.v4, and the other arm, Z, is subjected to the action ofl a spring, L,which-tends to hold saidlever in the position shown by dotted linesin-Fig. 9. At the same time this lever Z L' is'drawn downward to theposition shown in Fig. 1', a rotary inotion in the direction of arrow 2,Fig. 1, is imparted to mainshaft L by any suitable meanssuch, forinstance, as a clutch connected with the treadle-and such rotation ofthis shaft is limited'to one revolution by the said clutch or otherwell-known means. Such mechanism IIO being old, it forms no part of myinveniio and is not shown in the drawings.

On the slide .KQ and near the inner end thereof, is a tooth orprojection, la', Figs. 1, 2, 4, and 9, which is engaged by one arm, M,of a forked bellvcrank lever, M m, Figs, 2, 4, 5, and 9, the other arm,m, thereof being engaged by a spring-pressed .and pivoted trip-cam, M',carried by the crank-lever L Z; When the latter lever moves to theposition shown in Fig. 9 by dotted lines, the slide K' is drawn backagainst a stop cam or wheel, M2, mounted on the shaft L, and the chuck D-is ready to lreceive t-hc stud. The chuck is elevated by meanspresently to be described.

'To rotate the chuck when in its elevated position, I feather agear-wheel, D', thereto, which remains stationary while the chuck moveslongitudinally, by reason of stops at its top and bottom, and saidgear-wheel is engaged by a segmental and cogged driver, N,

Figs. 1,' 2, 3, and 5, which is pivoted at n to a hub of the easing."From this segmental 4driver extends an arm, N', containing a slot,

n', in which plays a vertical pin, n2, projecting from a slide, N2. Thisslide can move in ways at, formed in the casing, and carries on its endarollerstud, at, which is engaged by a cam, O, mountedon the main shaftL, which cam has a proper contour to move the slide` forward rlhe.drivingsegment N is moved in a forwarddirection, as indicated by arrow3, Fig. 2, by the action of the cam .0, Fig. 3,

and to the position shown in Fig. 5, where itis retained by a springbolt or catch, P, that projects 'from the casing F and engages adepression in the segment. The catch P is provided wit-h an extendingpin or projection, p,-

whereby said catch can be raised or withdrawn, so as to release thedriving segment N. rlhe said segment vlis returned to the position shownin Fig. 3 by the action of a spring, O', bearing against one end of the.slide N2 when the segment is released from the latch P. When thecrank-leverZL is moved toward the position shown in Fig. 9, and whennear the end of its stroke, a'projection, p', thereon engages' the pinon t-he latch Pand depresses the latter, whereby the driving segment isreleased and the'chnck D is rotated toits rcceiving position.V i

The driving segment N carries a vertically-y movable stud, C', which issubjected to the action of a spring-plate, c, Figs. l, 3, and 5. The endof said stud projects above the driving segment, and is adapted toengage with an arm, c', extending laterally from the driv ing-spindleg'of the conveyer C, so that when the segment moves in the direction ofarrow 3, Fig. 3, the stud carries said arm c" with it and rotates theconveyor-spindle (l, This rotation moves the conveycr so as to bring thelacing-stud in front of the inserting-bolt J.

From the stud C' extends a lateral arm, c2,

which is adapted to pass under a spring pressed triplever, C2, pivot-edin a post, C,

when the segment N moves toward its latch l?.

" On the crank-lever ZL', Figs. 2, 3, 4, and 5,

is a spring-pressed cam-lever, c, which engages one arm of thetrip-lever Gl when'said lever Z L' is depressed, thereby causing saidlever C2 to push the stud C downward and effect the release of thearm c'ot' the conveyer-spinvdle g. The conveyor is under the action of coiledspring Gti", Fig. 1, which causes it to turn in a direction opposite toarrow l, Fig. 7, and the inserting-bolt J of the conveyer is actuated toinsert the lacing-studinto the chuck D, said stud remaining in front ofthe Y bolt as the conveyor reverses. To raise the chuck from theposition/shown in Fig. 9, after the insertion of the lacing-stud intoits jaws, the driving-segment N carriesa projection or tooth, q, Figs.2, 3, 4, and K a projection or tooth, q'. These teeth are so arrangedthat when the segment N is in' the position .shown in Fig. 3, and theslide K' in its forward position, the driving-segment N can move to theposition shown in Fig. 5 without the teeth QUI rcoming into engagementwith each other; but when the crank-lever ZL' is depressed the slide K'is first moved backward to depress the chuck, and into the positionshown in Fig. 9, as. before described. On the subsequent release ofthelever'Z L the tooth q thereon `V`engages the tooth q' on the said slideand moves it forward to elevate the chuck, as in Figs. 1 and 2. y

` The punch ylt, Fig. 1, is vmounted in a hollow arm, F', ofthe casing,in adirect line with the-chuck D, and it `is actuated to impinge on thestud directly after the saine has been inserted into the work and Whilethe chuck is in its raised position. ln the example showndn thedrawings, the punch R is provided with an adjustable portion, r, whichis screwed into a threaded socket in a shank, r', and held secure afterthe, adj ustment by a setserew.. They punch can move in the direction ofits length, and is depressed by alever, R', pivoted at r2, one arm ofwhich engages the same, its other arm being acted on by the horizontalarm ot a bell-crank lever, It", pivoted at r3. The ver- -tical arm ofthis lever El is engaged by an ec centric roller-stud,r, secured tothe'face of .a disk or collar, R,on the driving-shaft, whereby saidcranklever is vibrated about its shaft.`

rllhe punch is withdrawn or raised by a spiral spring, rf, Fig. 1. i

The feeder A, Figs. -15 to 2,6, both inclusive,

5, and the slide` IOC vconsists of a circular casing or body containping a circular sleeve, `A?, which is suspended therein by a iiange, a,at its top, the lower edge ot' said sleeve being at -a distance abovethe bottom of the casing. This sleeve has an inner inclined face orwall, and located centrally with regard to the same is a conical hub,A2, which forms with the sleeve an annular receivingchaniber, S'. Thesleeve is partially closed at its top by a cover, a. rests in a support,A, secured to the arm F' of the machine, Fig. 7, and to the said casingThe casingy is secured a hopper, T, having a discharge orifice, t,communicating,with the receiving- `wheel e is secured to the shaftshaft, U, extends through the casinghub andl into the hopper, havingbearings in all of the same. On the upper end of this shaft is an`agitator, U l which kceps the lacing-studs from clogging and causes themto drop through the discharge-orifice t. An interniittentrotary motionis limparted to this shaft U from the main shaft L, Fig. 1, ofthemachine, as follows:

At the bottom ofthe shaft U, and below the casing, is secured aAratchetfwheel, U, which is engaged by a spring'pressed pawh'u, Figs-15,20, 21, carried by an arm, U2. This arm is loosely Secured to the shaftU, and can swing about thesame, and arod, u', extending from the same,projects through a slot in the support A4, Fig. 1, and is engaged by aforked lever, U, that is pivoted at n2, and is engaged on the lower sideofits pivot by a cam,r U*, having a suitable contour to give a vibratorymotion to said lever. A strong spring, uf", keeps theV lever pressedagainst the cam. The arm U2 vibratesbetween stops u"i and u?, Fig. 20,so that the pawl can advance only one tooth at each vibration and rotatethe shaft U correspondingly.

In order to prevent the-lacing studs from clogging up thedischarge-orifice t, a clearing lever, V, Fig. 16, is used,which isprovided with a number of teeth 'or prongs. lThis elearing-lever issituated directly above the dischargeoritce and is pivoted at o to thecoverl of the casing, and it is vibrated by a ratchet ortoothed whecLo,engaging with said lever, in conjunction with a spring, a2. The ratchet-U and rotates over the same. l,

To regulate the quantity of lacingstnds discharged, a gate, V, Fig. 19,is adjustably secured tothe bottom o f the hopper, which gate isprovided with a handle, n3, projectinglaterally. Aset-screw secnredinthe-bottom of the hopper and engaging with a slot in thc vgate permitsthe. adjustment of the same. In

the bottomof the feeder-casing is located a feed-plate, W, containing acircular series of cells,w, which are adapted to receive the lacingstudsentering the receiving y This feed-plateW is secured to the'shaft U androtates with the same, In a convenient point in the bottom of the hopperrIis formed a dischargebriiicaWV, of the same diameter as the cells w,and said discharge-oritiee'is at the same distance from the center asthe cells' in the feed-plate. The plate Wbeing rotated through a spaceequal to thedistance between the centers of two consecutive cells, w,the latter are brought successively in line w'ith the discharge-'orificeW', and the lacing-stud can pass through the same and into the feed-tubeA', connect-ing with the eonveyer C.

In order to insure a perfect align ment of cell the armiU, Fig.' 21.

act against the inclined and dischargeorifce, a stop, W2, Figs. 16 and18, is made to engage with one of the cells at ach movement of theplate. In this example said stop consists of a springpressed pintle, W2vwhich has bearings in a housing, 1v, and isaetuated by a level', @02,Figs. 15 and 20, said lever being engaged by a cam-surlaee,'w", on Thiscam-surface wl draws and holds the pintle out of engagement with thecells 1Q when the arm U2 is drawn forward y to cause the pawl u toengage a tooth, and the spring snaps the pintle into a cell as soon asthe feed-plate-W ceases to. rotate.

In order that the lacing-studs can pass ont of the dischargeoriiice Wonly in the proper position-that is, with their heads down and all suchstuds as have not been received by the cells w in such position, and forretaining. those in the cells that have been properly re ceived. 5 Forthis purpose the feed-plate W, -Figs'. 17, 18,22, 23, and 24, hasvertical annu lar grooves or depressions on each side of the cells to,Fig. 21, to form aprojeeting cell-ring,

W*, and from such depressions extend horizontal ways, or grooves w*- andw, extending entirely around the inner and outer peripheries oftheell-ring Wit; and intosaid grooves w3 and uf penetrate from each sideof the ring W*two jaws, Z Z', which are pivotcd at z z', respectively,to the sleeve A3 and the hub A. `The jaws Z Z are subjected to theaction ,of springs'vz2 and z,`which tend to force the same toward eachother. These jaws ZZ are directly opposite each other and extend-intothe cells lspiral up-I employ mechanism for ejecting successively as thefeedplate W rotates. In e this-example they are in a cell, wei, and itwill be observed that as the feed-plate rotates said jaws will bevibrated-that is, will be pushed apart to allow the lacing-stud in thecell to pass between the1n,and then close again as the feed-plateeeasesto move. Suppose, now, that a, lacingstud has entered one of thecells with and in this case it will be observed that the jaws Z Z willenter the socket b in such head from each-side and hold the same; but ifthe l lacingstud enters a cell with its spiral end down the jaws canobtain no-hold on the lacing-stud, as the projecting point or screwcannot be grasped by the jaws. l

An` ejector consisting of an arm or shank, B', vhaving arnese, bj,-whieh projects upward an d into the cell wil: between the jaws Z Z,actsto expelall such studs as are not held by the j awsl The ejector ispivoted at b, and plays through a slot in the bottom of the hopper. Aspring-plate, b5, keeps its shank. pressed upward and against the bottomof the feed-plate. In the said bottom, Figs. 22 and 24,-is a groove, b,the divisions of the same, formed by the cells, being tapering in theproper direction to forni cam-surfaces, `which or sloping. surfaceofthe-nose b3 to depress the ejeeting-arm as the feed-plate rotates. tionof its' spring-plate b5, snaps inte the succonstantly The'ejectoiydue iothe ae- EIO its head down and such-cell reaches thcjaws, l

vis

cessivc cells with sufficient force to eject such' studsjas are notheldby tliejaws-that is, those which have not properly entered thecellswhile those which have so entered the cells are `not ejected, and,passing to the discharge-orilice N are discharged in their turn. Inorder, however, that such studs as are ejected may not accumulate aboutthe cell art, and also to turn them in order to facilitate the chance oftheir entering another cell in the proper p osition, I provide adistributing brush-wheel, B2, which rotates as the feed-plate \Vrotates, and the ejected lacing studs coming into contact therewith arepromptly thrown back into the space of receiving-chamber S. Thisbrushwheel also prevents any of the lacing-studs not in cells frompassing over to the dischargeorilice, the access of such studs bei ngprevented on the other side of' said orifice by a diaphragm orpartitiomBii, cxtendi ng across the receivingchaniber from top tobottoni at a point between this discharge and thedischarge-orificet ot'the hopper T, Fig. 16. In the example shown in the drawings the brush isactuated as follows,Figs. 15, 16, and 17: The brush-wheel is mounted onan arborhf, which has a bearing in a fraaie attached to the casing. Tothe outer end of the said arbor is firmly attached a gear-wheel,F*,

which is in engagement with a gear-wheel, F2, 1

that rotates about a stud, f', on the frame attached to the casing. Athird gear, F3,en'gagcs with thegear F2, thestaldsff'l of the last twogears being in the same horizontal linc. From the studs ff ot' saidgears F`Z F3 are loosely swung arms l!" F". the free ends of which arejoined by a link, F. .These arms carry springpressed pawls f f which areadapted to engage with the teeth [of the respective gears F2 F, torotate the latter in the direction of the arrows marked thereon in Fig.15, but to leave them umlistnrbed when said pawls are moved in anopposite direction. The arm F'l is connected by a universal joint to alink, Dt, the other end of whichl is connected by a similar joint to alever, D, on a vertical rock-shaft, D On the upper end of said shaft Diis an arm, d', which projects inwardly through a slot in the casing, andis successively engaged by pins d, arranged on the feed-plate W, as thelatter rotates. A spring, E5, connected with the second arm ot' thelever D", returns4 the lever after its disengagement by the successivepins d". XVhen the arm d* is moved by one of the pins d", thepawl-fraine F* F" is moved in the direction ot" arrow 4, Fig. if, andthe pawlf, engaging the gear F, moves it in the direction ofthe arrowmarked thereon. The motion .is transmitted through .gear Fl to the gearF, and the brush is rotated in the direction of arrow 5. As the pin direleases the arm d* the pawl-frame FL F" is rapidly moved by the springE in an opposite direction, the gear F" is rotated in the direc` tion ofthe arrow thereon, Fig. 15, and the brush is rotated in the samedirection as be-y fore, but with a greatly-accelerated velocity. Thisaccelerated rotation ot' the brush-wheel takes place just as the ejectorexpels a lacingstud, if such has not been properly received by the cell,and the lacing-stud thus ejected is thrown out into the spaceof thereceiving-chamber. The lacing-studs which are retained in the cells passthe jaws Z Z', and on arriving in line with the discharge -oriticc Wdrop through the same and into the feed-tube A', from which they enterthe conveyor from 'time to time.

The operation of the inserting mechanism is as follows:- As shown in thedrawings', in Figs. 1, 2, 3, and 4., the operating parts arein aposition in which the chuck D contains a lacing-stud and is in itselevated position. Y

When the crank-lever ZL is now depressed, as shown in the said figures,the main shaft L is caused to make one complete rotation and thenv stop.During this rotation the drivingsegment N is moved in the direction ofarrow 3, Figs. 2 and 3, about its pivot, and at the end yof its movementis locked by the latchP, Fig.

5. The eonveyer C, Figs. 6 and 7, before the movement of theshaft, hadreceived a lacingstud from the feeder, as in Fig. 6. The springstud C onthe driving-segment engages the arm c2 of the conveyor and rotates thelatter as tlie segment rotates, thereby bringing the lacing-stud in linewith the chuck D,and holds itin readiness for subsequent insertion. 'Thedriving-segment N in its ymotion rotates the l chuck a completerevolution, and the lacingstud therein is screwed into the material.

The punch D now descends'and rivets over` the spiral on the lacing-stud.The shaft hav ing completed an entire revolution, the treadle isreleased and the crank-lever Z'L is returned ltoward the position shownin Fig. 9 bythe spring L2. In this stroke of the crank-lever the slideK', Figs. 2 and 4, is drawn back against the flat portion of' the hub orsleeve M2, whereby the punch D is lowered to its receiving position alittle later, or about at the same time the arm c'l of theconveyer-shaft is released, and, due to the action of the spring G21,Fig. 1, the conveycr cover is rapidly moved in the directionof the arrowl, Fig. 7, to the position shown in Fig. 2, or its receiving position,and immediately on the commencement of this reverse movementthcbolt-Jinserts the lacing-stud into the chuck, such stud having remained infront of the bolt when the conveyer started to rotate inthe saiddirection of arrow 3, Fig. 3. y The crank-lever now releases thedrivingsegment, which returns to the position shown in Figs. 2 and 3 androtates the chuck. This rotation' has, however, no useful effect; and,if desired, the chuck could be so geared as not to be rotated by thesegment in this stroke of the same. The seg'- ment onl its releasethrows the slide K inward by reason ot' the respective teeth q q', Fig.5, engaging with each other, and such motion of the slide K elevates thepunch D to its inserting position, Fig. 7, and the machine inof thecrank-lever.

` The feed-tube A2 is provided with anarrow longitudinal slot, in orderthat the number of lacing-studs therein can be observed.

To prevent any part of the feeder A, Fig. 1 being injured in case alacing-stud should get caught or wedged in any manner, I cause the camU" to move the actuating-lever U3 on its non-working stroke-that is tosay, that stroke iu which the lever draws back the 'pawl a to engagewith a new tooth-while power for the actual rotation of the shaft U isfurnished by the strong spring a5, so. that in case of accident thefeeder would be subjected only to the slight strain caused by the saidspring.
